What is indicated by alternating red and green signals for aircraft in flight?

The indication of alternating red and green signals for aircraft in flight is a general warning signal to exercise extreme caution. In aviation signaling, colors and their patterns are used to convey specific safety messages to pilots. The alternating red and green signals communicate to the pilot that they should be particularly vigilant due to potential hazards or unstable conditions in the area. This warning prompts the pilot to increase their situational awareness and prepare for conditions that may require heightened precautions, rather than suggesting permission to proceed or indicating maintenance needs. Understanding this signaling is crucial for ensuring safety and effective communication within the airspace.
